+ * tlist - typesafe double linked list routines
+ *
+ * The list header contains routines for manipulating double linked lists;
+ * this extends it so you can create list head types which only accomodate
+ * a specific entry type.
+ *
+ * You use TLIST_TYPE() to define the specific struct tlist_<name>, then use
+ * the tlist_* variants of the various list_* operations.
+ *
+ * Example:
+ * #include <err.h>
+ * #include <stdio.h>
+ * #include <stdlib.h>
+ * #include <ccan/tlist/tlist.h>
+ *
+ * // Defines struct tlist_children
+ * TLIST_TYPE(children, struct child);
+ * struct parent {
+ * const char *name;
+ * struct tlist_children children;
+ * unsigned int num_children;
+ * };
+ *
+ * struct child {
+ * const char *name;
+ * struct list_node list;
+ * };
+ *
+ * int main(int argc, char *argv[])
+ * {
+ * struct parent p;
+ * struct child *c;
+ * unsigned int i;
+ *
+ * if (argc < 2)
+ * errx(1, "Usage: %s parent children...", argv[0]);
+ *
+ * p.name = argv[1];
+ * tlist_init(&p.children);
+ * for (i = 2; i < argc; i++) {
+ * c = malloc(sizeof(*c));
+ * c->name = argv[i];
+ * tlist_add(&p.children, c, list);
+ * p.num_children++;
+ * }
+ *
+ * printf("%s has %u children:", p.name, p.num_children);
+ * tlist_for_each(&p.children, c, list)
+ * printf("%s ", c->name);
+ * printf("\n");
+ * return 0;
+ * }
